Use vertical centrifugal CR pumps for reliable efficiency

The CR pump is built from cast iron with all wetted parts made of AISI 304 grade stainless steel, making this pump suitable for non-corrosive liquids. With world-class efficiency, flows up to 320 m3/h and 40 bar working pressure, the CR is the perfect virtical centrifugal pump for a range of demanding applications, such as liquid transfer, circulation and pressure boosting of cold or hot water, aqua-farming and field irrigation.

Tight controls over every aspect of the production process are the secret behind the reliability of the vertical centrifugal pump CR. Grundfos production is certified in accordance with the strictest international standards (ISO 9001) and is subjected to rigorous process control. Each CR pump is tested for performance, power consumption and static pressure before leaving the factory.

A number of ATEX-approved CRN pumps are available, according to the locality, hazard and likelihood of a dangerous situation occurring. ATEX-approved pumps are for use in potentially explosive atmospheres. Explosive atmospheres consist of air and combustible matter such as gases, vapours, mist or dusts in which the explosion spreads after ignition.

The all-round performer

With 16 flow sizes and hundreds of pressure sizes to choose from, you can be sure that there is a pump to match your job requirement. 

High hydraulic efficiency. Performance is optimised from fluid mechanics insights provided by extensive simulation-driven design and verification. 

A wide range of connection types and flange sizes to choose from means the pump can be connected to any system.

Very long-lived bearings, thanks to hardwearing materials and a wide range of options for difficult liquids.
